The plant is made up of root and shoot structures that contain parts that enable the plant to grow and manufacture its food.
The structure and function of plantsThe structure of plants is made up of tissues such as:
phloemstomaxylemguard cellsdermalground andvascular.The three characteristics that all species being to the plant kingdom have in common are:
They are non-motile,They make their food hence are called autographs; andTheir cell walls are made sturdy by a material called celluloseThe tropical plants have more stomata than the desert plants. This helps the desert plants to reduce water loss.
Some defects occur when there is damage to the vascular tissues such as the xylem( plant will not be able to transport water from the soil through roots to leaves) and phloem (nutrients produced during photosynthesis will not be able to reach every part of the plant body).
The dermal tissue of plants and the human skin performs protective roles to the underlying tissue organs.
A plant won't be able to survive because it won't absorb water and nutrients from the soil and transport it upwards to all the parts of the plant.
Flowering reproduction in plants takes place through the following steps:
Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination. Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.Flowers benefit other organisms in our environment by creating more carbon dioxide-absorbing and oxygen-radiating plants.
The flowers contain male reproductive organs called stamens and female reproductive organs called pistils.
The process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote.
Most flowers are bright in color because they are like advertisement signs for pollinators.

Which of the following results when homologous chromosomes cross over in meiosis?
Two sister chromatids get tangled, resulting in one re-sequencing its DNA.
DNA repair machinery alters maternal alleles so they match paternal ones
Two sister chromatids exchange identical pieces of DNA.
Corresponding segments of non-sister chromatids are exchanged.
When homologous chromosomes cross over in the process of meiosis, the corresponding segments of the non-sister chromatids are exchanged. Thus, the correct option is D.
What is Crossing over?
Meiosis is the process of cell division in which the chromosomal content of the cell reduces to half. This division is also known as reductional division. Meiosis is divided into two parts: Meiosis I and Meiosis II.
Meiosis I is divided into four phases which are Prophase I, Metaphase I, Anaphase I, and Telophase I. Prophase I is further divided into five stages which are Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis. Crossing over of chromosomes takes place during pachytene stage.
Crossing over or the chromosomal crossover is the exchange of the genetic material during the process of sexual reproduction between the two homologous chromosomes' non-sister chromatids which results into the formation of recombinant chromosomes.
Therefore, the correct option is D.

·Why does it make sense that blood flow varies throughout different organs
It is important that blood flow varies throughout different organs because of differences in the metabolic activities of the different organs.
What is the circulatory system?The circulatory system refers to the system of organs and tissues which are involved in the circulation of blood around the body.
The circulatory system performs the essential function of delivering nutrients to tissues and cells as well as removing metabolic waste from them.
Since the different organs in the body perform specialized functions, some organs are actively involved in metabolic activities, therefore need greater blood flow.
Therefore, blood flow varies throughout different organs because of differences in their metabolic activities.

What is meant by wildlife? How is wildlife important for us?
Answer:
Animals that grow or live in the wild without any human interference are known as wildlife. Importance of wildlife is as follows: Wildlife helps keep the food chain in place and thereby maintain ecological stability.
Explanation:
The term "wildlife" refers to all living organisms that exist in their natural habitat, without any human interference. It includes animals, birds, plants, and other organisms that thrive in forests, oceans, deserts, and other natural environments.
Wildlife is important to us in several ways:
1. Biodiversity: Wildlife plays a crucial role in maintaining biodiversity. Each species contributes to the intricate web of life, and the loss of even one species can have a significant impact on the entire ecosystem. For example, bees play a vital role in pollination, which is essential for the reproduction of many plant species.
2. Environmental balance: Wildlife helps to maintain a balance in ecosystems. Predators, such as lions or wolves, help control the population of herbivores, preventing overgrazing and maintaining the health of vegetation. This balance ensures that resources are distributed appropriately and prevents the dominance of a single species.
3. Ecosystem services: Wildlife provides various ecosystem services that benefit humans. Forests, for instance, serve as a habitat for countless species, help regulate climate, filter air and water, and provide resources like timber and medicinal plants. Wetlands act as natural filters, purifying water and reducing the risk of floods.
4. Cultural and recreational value: Wildlife also holds significant cultural and recreational value. Many communities have strong cultural connections to specific wildlife species, and these species may play important roles in their traditions, rituals, and beliefs. Additionally, observing and interacting with wildlife through activities such as bird-watching or safaris can bring joy and a sense of connection to nature.
5. Scientific and educational purposes: Studying wildlife helps us gain knowledge about different species, their behavior, and their roles within ecosystems. This understanding is crucial for conservation efforts and managing natural resources sustainably. Wildlife education also fosters a sense of environmental awareness and encourages people to become responsible stewards of the planet.
Hence, wildlife encompasses the diverse range of organisms found in their natural habitats. Its importance lies in its contribution to biodiversity, environmental balance, ecosystem services, cultural value, recreational opportunities, and scientific knowledge. Preserving and protecting wildlife is essential for the well-being of both the natural world and human society.

The parents have the following alleles.
Bb
Bb
What color hair do the parents have?
A. One has blonde and the other has brown
B. Brown
C. Blonde
d. unable to determine
Given what we know, we can confirm that the parents have brown hair.
This has to do with how dominant alleles work. When an allele is dominant, it is because, in the presence of mixed alleles, this trait will always be the one reflected in the phenotype of the individual. Since the parents possess an allele for brown hair and one for blonde, but brown hair is dominant, both parents will have brown hair.
Therefore, we can confirm that both parents will have brown hair due to the dominant nature of the brown hair allele.

Sally made a diagram to show one way that Earth's systems interact near a volcano
1. Identify the process that sally is moldering in her diagram
2. Explain how the individual parts shown in the model come together to form a cycle
The process that Sally is modeling in her diagram is the "Role of Volcanoes in the Earth's Systems". This particular system is called "the Cycle of Rock and Soil formation"
How do the individual parts of the model form the cycle?The cycle of soil formation starts with the production of molten magma by the volcano.
The magma solidifies and cools, then they are transported, deposited and go through lithification.
After lithification, they become sedimentary rocks, and then through exposure to pressure, they become metamorphic rocks.
Over the years, as more and more layers are deposited onto the metamorphic rocks, pressure and heat build up creating molten magma.
The magma creates igneous rocks which after many years may be produced again as molten magma through an active volcano.

It is inefficient because less energy is needed at the top.
It is very efficient because most energy is made by producers
Only a portion of energy from vegetation makes it to a person.
Answer:
It is very efficient because the person can eat less.
Explanation:
the common knowledge answer
Only a portion of energy from vegetation makes it to a person. The correct option is D.
What is energy efficiency?The definition of energy efficiency is the use of less energy to carry out a task or achieve a goal.
Ecological efficiencies at each trophic link determine the food chain efficiency (FCE), which is calculated as the percentage of energy fixed by primary producers that is transmitted to the top trophic level.
The energy supply accessible to trophic level N+1 divided by the energy used by trophic level N is the definition of ecological efficiency.
Only a percentage of the energy from vegetation makes it to a person, which best sums up the efficiency of energy transmission in this situation.
Thus, the correct option is D.
